WASHINGTON – Washington Nationals outfielder Jose Guillen should begin rehabilitating his left shoulder in a week and is expected to be ready for the regular season.

Guillen should be able to start swinging a bat in about three months, Nationals spokesman John Dever said Friday.

Guillen had surgery Monday.

He hurt the shoulder on a headfirst slide in June but never went on the disabled list.
